<p>说了两篇理论，是时候实操一下了。找个实例说说。<br>假设我们要用ReactJS实现一下列表<br>由于React 是组件化的元素，所以这个时候你需要分解一下这个页面<br><img src="/blog/2018/09/23/React-with-TypeScript-系列-三-实战篇/20160113202537877.png" alt></p>
<p>如图所示 ，我会分解成<br>头 head - 这是一个滚动的广告，是页面的头部<br><img src="/blog/2018/09/23/React-with-TypeScript-系列-三-实战篇/20160113203022020.png" alt></p>
<p>尾foot - 这是一个底部，负责Tab<br><img src="/blog/2018/09/23/React-with-TypeScript-系列-三-实战篇/20160113203242061.png" alt></p>
<p>最后就是我们所说的列表catalogList了<br><img src="/blog/2018/09/23/React-with-TypeScript-系列-三-实战篇/20160113203455098.png" alt></p>
<p><img src="/blog/2018/09/23/React-with-TypeScript-系列-三-实战篇/20160113204437992.png" alt></p>
<p>按照这个划分我们的页面是由<code>&lt;head/&gt;&lt;catalogList/&gt;&lt;foot/&gt;</code>按顺序构成，若果再细分CatalogList 你可以针对每个行在划分成CatalogItem组件。而CatalogItem里的再划分是没有必要了。<br>我们开始搭建我们的平台</p>
<ol>
<li>开发工具和环境搭建<br>Visual Studio Code 是我的个人选择，当然你可以用Atom,也可以用SublimeText。如果要编译tsx文件你必须对VisualStudio Code 进行配置（这里有个前提是你需要把我的第一篇文章看了，因为你需要安装好react.d.tsd文件）, 我在asp.net 5 模版下构建例子，添加了一个简单的Index.tsx文件。<br><img src="/blog/2018/09/23/React-with-TypeScript-系列-三-实战篇/20160113210908974.png" alt></li>
</ol>
<p>当我需要编译这个文件时（mac 下cmd＋shit＋B，windows下自己找文档吧），系统会要求你创建一个编译环境<br><img src="/blog/2018/09/23/React-with-TypeScript-系列-三-实战篇/20160113211523708.png" alt></p>
<p>你点击Configure Task Runner, 就会生成task.json,<br><img src="/blog/2018/09/23/React-with-TypeScript-系列-三-实战篇/20160113211838454.png" alt></p>
<figure class="highlight json"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br><span class="line">6</span><br><span class="line">7</span><br><span class="line">8</span><br><span class="line">9</span><br><span class="line">10</span><br><span class="line">11</span><br><span class="line">12</span><br></pre></td><td class="code"><pre><span class="line">&#123;</span><br><span class="line">    <span class="attr">"compilerOptions"</span>: &#123;</span><br><span class="line">        <span class="attr">"jsx"</span> : <span class="string">"react"</span>,</span><br><span class="line">        <span class="attr">"outDir"</span>: <span class="string">"./wwwroot/ts/"</span>,</span><br><span class="line">        <span class="attr">"target"</span>: <span class="string">"es5"</span>,</span><br><span class="line">        <span class="attr">"module"</span>: <span class="string">"commonjs"</span>,</span><br><span class="line">        <span class="attr">"sourceMap"</span>: <span class="literal">true</span></span><br><span class="line">    &#125;,</span><br><span class="line">    <span class="attr">"files"</span>: [</span><br><span class="line">        <span class="string">"./wwwroot/ts/Index.tsx"</span></span><br><span class="line">    ]</span><br><span class="line">&#125;</span><br></pre></td></tr></table></figure>
<p>回到我们的task.json把args那行替换为”args”:[“-p”,”.”]即可，<br><img src="/blog/2018/09/23/React-with-TypeScript-系列-三-实战篇/20160113221307497.png" alt></p>
<p>之后在Index.tsx重新按cmd+shit+B 就可以对tsx进行编译，生成Index.js,Index.js.map两个文件了。<br><img src="/blog/2018/09/23/React-with-TypeScript-系列-三-实战篇/20160113221612766.png" alt></p>
<p> 二. 写代码去<br> 按照之前分析的方法我们去构建tsx其实很简单(我这里先做一个静态的，动态的之后系列再谈)<br> Head组件如下：</p>
<figure class="highlight xml"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span

<p>回到default.html,你所做的就是添加Index.js和把其他css添加进去即可了。<br><img src="/blog/2018/09/23/React-with-TypeScript-系列-三-实战篇/20160113230812747.png" alt></p>
<p> 最后一步，当然是运行看看，感觉不错吧。<br><img src="/blog/2018/09/23/React-with-TypeScript-系列-三-实战篇/20160113230812747.png" alt></p>
